Shock absorber for a forearm protecting device

ABSTRACT

This invention concerns a forearm protecting and shock absorbing device ( 120 ) covering the forearms from the base of the elbow to the wrist providing protection against attacks with truncheons, even with bladed weapons in various situations. The device may cover only the cubital part ( 30 ) of the forearm which is the vulnerable part. The whole device is supported on a covering portion ( 132 ) with a surface with a wave-absorbing cushion ( 134 ) consisting of Kevlar fibers or similar fibers capable of dispersing a shock wave over a larger surface. The covering portion is provided with sharp-edged points ( 128 ) inserted within it.

BACKGROUND OF THE INVENTION

This invention concerns the security domain and particularly forearmprotecting devices which are used as means of self-defense or as amethod of controlling criminals.

OBJECTIVES AND ADVANTAGES

A general objective of this invention is to provide a device forprotecting forearms and comprising a covering portion with a surfacemade from composite materials and provided with sharp-edged pointsinserted on a shock-absorbent cushion wrapping. The device is light andallows someone who carries it, like an agent of safety or a policeofficer, to keep his hands free and to control a criminal by a techniqueof control by a pain. The device goes under clothing and offers a meansfor covering the ulnar side of a forearm for defense, and the radialside to retain or immobilize a criminal. The device is made in differentlengths and each piece can be encase in another piece to cover a part ofthe forearm or all the forearm from the wrist to the elbow.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

In the following description and in the drawings included, the similarnumbers refers to identical parts in the various figures.

FIG. 1 shows at a top part a sharp-edged point 130 of two pillar legs ofa defensive rods 128, with an acute part 126 disposed at its base on ashock absorbing portion 132 provided with a flat surface 134 made fromcomposite materials such as: resistant plastic, polycarbon or otherlightweight material. A concavity 124 is for the purpose of spreadingthe shock absorbing portion 132 over a bottom 122. The bottom has anextension 133 appearing as a slope.

A lower part of FIG. 1 shows a top view of the combination defensiverods 128 embedded in a support 120. A laid out rectangular piece of alength 136 and embedded longitudinally at the ends one in another, oneend being a female part 140 and another end a male part 138. A joint 144allows attaching along a forearm one device with another device byinserting joint 144 of the first device in the hole 142 of the seconddevice. The extensions provided as a male part 138 and female part 140are coming essentially from the cutting of the slope 133. A removal part129 is for the purpose of cutting down the weight of defensive rod 120,thereby creating two legs 128 under the sharp-edged point 130.

FIG. 2 shows a front view of a triangular rod 131 which is of atriangular form with a thickness delimited by sides 146 and 148,external and internal. The sharp-edged point 130 is appearant as well asthe removal part 129.

FIG. 3 shows a cut view of a defensive rod 127 which is of a rectangularform 190 with a thickness delimited by sides 146 and 148 and insertedfrom the base 151 to the length 153 on the shock absorbing portion 132made from composite materials such as: resistant plastic, polycarbon.One sees the removal part 129.

FIG. 4 shows the protecting device 120 inserted in membranes 156 aboveand 154 below. The shock absorbing portion 132 is disposed on internalface 152 of the membrane 154. One sees between two devices a mobile partto facilitate junction between two sharp-edges. The shock absorbingportion 132 wraps the forearm with bottom part 122 who is in contactwith the skin of the arm.

SUMMARY OF THE INVENTION

A combination of wrappings 120 for a limb being protected by defensiverods 128, the combination comprising:

-   -   a first membrane 154, for adapting to the skin,    -   a second membrane 156 for overall covering,    -   a shock absorbing portion 132 on which the defensive rods 128        are posed,    -   the defensive rods 128 are inserted between the two membranes        154, 156 and disposed at their base on the shock absorbing        portion 132.

The shock absorbing portion 132 is being made from composite materialssuch as: resistant plastic, polycarbon or other lightweight material,and is provided with a flat surface 134 adapted to receive an impactfrom the defensive rod 128.

The shock absorbing portion 132 comprises at its ends 133 means formutual insertion 138, 140 for continuous wrapping around a limb and isprovided with a receiving portion 151 and a bearing distance 153 therebycreating a 90° angle support.

The defensive rods 128 comprise a removal part 129 thereby releasingfoot bases 151 with two pillar legs 128 and they are provided with anacute angle 126 for being retained by a reentrant portion 135.

The shock absorbing portion 132 comprises a bottom part 122 with aconcavity 124 thereof, the spreading of extension 133 of the shockabsorbing portion 132 elongating the concavity 124 and releasing thereentrant portion 135, thereby permitting the securing of the pillarlegs 128.

A device comprising an apex sharp-edge point 130 and two defensive legs127 originating from the apex 130. The device is provided with a shockabsorbing portion 132 for being used in combination with means forwrapping a limb and is intended to be used as means of self-defense orfor attacking a criminal by applying a pressure using an armed limb. Thedevice being installed inside those means for wrapping. The shockabsorbing portion 132 comprises:

-   -   a bottom surface 123 adapted to be in contact with the skin,    -   receiving portions 151 adapted to receive the two legs by        inserting them from their base to a certain length 153, thereby        locking and securing the legs for receiving an impact from the        defensive leg rods,    -   a concavity portion 124′ between the two legs 127 to facilitate        the insertion of the two legs in the shock absorbing portion        132.

The two defensive legs 127 being in metal or other hard material andbeing defined in a reversed V-shape with a thickness delimited by twosides 146, 148 and a removal part 129 between the two legs, asharp-edged point 130 defining the junction between the two legs 127.
